The INTErnational Gamma-Ray Astrophysics Laboratory

INTEGRAL,
was launched in October 2002 aboard a Russian Proton rocket, and is
providing a new insight into the most violent and exotic objects of the
Universe, such as neutron stars, active galactic nuclei and
supernovae. INTEGRAL is also helping us to understand processes such as
the formation of new chemical elements and the mysterious gamma-ray
bursts, the most energetic phenomena in the Universe. Environments of
extreme temperature and density, near the event-horizons of black holes,
are a major topic of study with INTEGRAL.

These studies are possible thanks to INTEGRAL's combination of fine
spectroscopy and imaging of gamma-ray emissions in the energy range of 15 keV
to 10 MeV (using the SPI and IBIS instruments) and concurrent monitoring in
the X-ray band (4-35 keV) using JEM-X, and in the optical (500-600 nm) band,
using the OMC.

A project of the European Space Agency
INTEGRAL, serves an international Guest Observer
community. Participation by U.S. astronomers was
supported by a Guest Observer Facility (GOF) at the NASA/Goddard Space
Flight Center (GSFC) from the mission start until October 2010. Since
then, the mirroring of the European INTEGRAL Public Data Archive into
the HEASARC has been continued by the HEASARC.

INTEGRAL AO-17 Schedule Announced(29 Jan 2019)
The ISOC is preparing the next call for proposals requesting INTEGRAL observing time. The AO-17 release will be on 25 Feb 2019 with
proposals due on 5 April 2019 (14:00 CEST).

OSA 11.0 Release(24 Oct 2018)
The INTEGRAL Science Data Centre (ISDC), the INTEGRAL instrument teams, and the INTEGRAL Science Operations Centre (ISOC)
have announced the release of the
Offline Software Analysis (OSA) version 11.0 . Several major improvements have been made in this new release.
It is important to note that OSA 11.0 for IBIS is currently limited to data starting from 2015-12-26 (start of revolution 1626).
For earlier data, the user should use OSA 10.2 with the limitations described in the user manual.

12th INTEGRAL Workshop and 1st AHEAD Gamma-Ray Workshop(19 Sep 2018)
The 12th INTEGRAL Conference will be organized together with the 1st AHEAD Gamma-Ray Workshop on 11-15 February 2019:
"INTEGRAL looks AHEAD to Multi-Messenger Astrophysics".
It will be hosted by the Campus Biotech, in Geneva (Switzerland).
This conference will discuss recent developments in high-energy astronomy,
with particular emphasis on its role in multi-messenger astronomy.
Further information including deadlines can be found at the above link.

The HEASARC mirror to the INTEGRAL Public Data Archive now contains data through the January 25, 2019
public data release (revolution 1903). It also contains all data from recent observations for which
the PI has allowed the data to be made public earlier than the 1 year proprietary period.
